This invention relates to' in'ountingbrackets and 1 more-particularly toimprovements in indieater inount n brackta 'although certainfea- 1auras: therbf- -inay -be" inployed with equal advantage fonbtherpurposes.

A still further object is to provide an offset integral indicatormounting bracket with compl terotar'y attachment at both ends so that acomplete range of adjustment between the in- 5 dicator and'mount ispossible in both longitudinal and transverse relation.

- 1 F.-Sti1l a:further object-is to provide-anindicaitorzoifsetsmounting bracket having a split resili ent-connectionat both ends thereof to render such readily interposable between theindicator xandthe fixed support to insureimaximum acpce'ssibility of theindicator to the parts to be .iimeasured.

V The structure selected for illustration is not *-intended'to serve asa limitation upon the scope 3'5 'or teachings of the invention, but isinereiy llu'strative thereof. There may be considerablevariationsan'dadaptations of all or part of the F "teachings dependingupo'nthedictates of commercial practice. The present embodiment com- 40prises a horizontally disposed elongated straight "-"--'arm ""or'==shank I0 which is of substantially rectangularcross section toterminate in an indicator -attacliing end. The indicator attaching 1end-comprises in't'his instance, a substantially circular:extremity IIin the plane thereof to pr'ovidea -vertical bore l2 threaded as at it;to rceive' a corresponding1y threaded shank i l comprising the low'erextremity of a post 15 which ='has "a:-split circular indicator shankreceiving ring? l-S atits upper end for frictional connection v'v ithth'e shank H of a standard measuring indic'ator I8.

Thenieasuringindicator i8 isrotatableabout lts lorigitud-inal axis inthe frictionals'plit supporting riiig l6 0f standard construction. The

split indicator supporting ring I6 is rotatable about its vertical axisby reason of its threaded shank l4 connecting with the threaded verticalbore l2 in the bracket mount circular extremity l I. The circularextremity H on the indicator mounting shank H] is slitted as at H! inthe outer region thereof preferably though not essentially along itslongitudinal axis to provide a frictional threaded connection with thepost shank M. This frictional engagement is enhanced by another slitthat communicates with an aperture 2| provided in the connecting end ofthe shank [0, thereby establishing an effective frictional connectionbetween the threads l3-l4 of the mount end II and the indicator post 15to maintain them in rotary adjusted relation.

The shank IU of the bracket mount terminates at its other extremity inan upwardly offset head 22 which is integrally connected therewith toprovide just sufficient space for the large head end of the indicator i8(Figure 6). The mounting bracket head 22 extends upwardly for a distancewithin the limits presented by the largest depth of the indicator It sothat the latter may be mounted in line with the longitudinal axissupporting line of the mounting bracket head 22.

In the present embodiment, this is efiected by presenting an elongatedhorizontal bore 23 within fixed complemental resilient jaws 24comprising a frusto-conical horizontal extension 25 on the head 22. Theresilient jaws 24 are defined by cross-slits 26 milled or otherwiseprovided horizontally through the frusto-com'cal head extension 25 alongthe axis of the bore 23. The crossslits 25 terminate in a transverseaperture 2'! in the head 22 to increase the resiliency of the jaws 24.This provides for the necessary resiliency in the jaws 24 tofrictionally engage a horizontal post or stud 28 adjustably carried in astandard bracket 29 which is vertically adjusted along a standard 30anchored to a base 3|, the parts 28, 29, 30, and 3! being of standardconstruction and part of a gauge or indicator mounting bracket that isusually used for measuring in conjunction with the indicator !8.

As shown, the head 2'2 of the bracket I8 is provided with a taperedsurface 32 proximate to and corresponding in inclination within forwardsurface 33 of the standard indicator l8 so that there will be sufficientspace for the full mounting movement thereof on the bracket mount (0without the latter being larger in size than is otherwise necessary. Thestandard indicator I8 usually terminates in a tapered end 34 having afeeler finger or detent 35 pivoted thereto through a ratchet connection(not shown) so that the feeler 35 can be displaced at any angularposition. This adjustment coupled with the ability to rotate theindicator I8 with its post l5 transversely of the bracket mount shankIB' (shown in dotted outline in Figure 5) as well as to all intermediatepositions of adjustment between these limits coupled with the completerotary adjustment of the bracket mount l0 and its rigid head 22 relativeto the horizontal supporting stud 28, and the axial rotation of theindicator l8 itself within the split collar ring I6, affords a fullcombination of adjustments for the indicator I8 with the mount ill orrelative thereto for complete access without obstruction by thesupporting brackets or arm In.

It will be apparent that a very simple, compact, and inexpensive bracketmount has been provided which will afford a full range of universaladjustment for an indicator I8 or the like relative to its supportingstandard 30 Without providing any obill 4 struction beyond the confinesof the indicator l8 itself.

While I have illustrated and described a preferred embodiment of thisinvention, it must be understood that the invention is capable ofconsiderable variation and modification without departing from thespirit of the invention. I, therefore, do not wish to be limited to theprecise details of construction set forth, but desire to avail myself ofsuch variations and modifications as come within the scope of theappended claims.
